Presentation Transcript

  1. Instruments used Particle accelerator: Boost particles to high energies and make them collide. Flagship is the 27km in circumference Large Hadron Collider (LHC), which is just the last in a chain of accelerators Detectors: Gigantic instruments that observe and record the results of the collisions (particle trajectories, energy, charge…) Computers: Collect, store, and distribute around the world the large quantity of data collected from the detectors for data analysis using the WLCG

  2. IT Department Structure Department Infrastructure WLCG openlab Security EC Projects Collaboration, Devices& Applications Storage Databases Compute & Monitoring Communication Systems Computing Facilities

  3. CERN Data Centre(s) Geneva + co-location (Wigner) Overview 3.8MW (~2.8MW) + 2.7MW (~1MW) 15 000 servers 230 000 cores 2 500 disk arrays 90 000 disks 280 petabytes of disk 40 routers and 1 300+ switches Procurement (average) 20% annual refresh Investment 2016/2017: ~15 MCHF / year

  4. CERN Data Centre Technologies currently used: Chillers Cold aisle containment Hot aisle containment Air and water cooled racks Intelligent PDUs UPS systems Adiabatic air cooling In-house monitoring and limited experience with commercial DC monitoring systems

  5. CERN Data Centre Challenges: Maximise the usage of current DC with the existing limitations on power and cooling Prepare for a needed increase in capacity of more than one order of magnitude for the 2025 timeframe

  6. Data Acquisition and Trigger farms Each of the four LHC experiments have significant data centres near the detectors. 1-2MW data centres with ~2000-4000 servers Two experiments (LHCb, ALICE) are installing new container-based data centres in 2019-20.

  7. Data centre and campus communication systems Routers : 250 Star points: 692 Switches 4k Wifi points 1.2k4-5k Annual investment 2016/2017 for switches and routers: 1.5 MCHF + Fixed & mobile telephony (4G/5G, private LTE, LTE/Wi-Fi integration) plus digital radio (TETRA).

  8. Outlook 2018-2022 Estimates: 2018 - 2019: Servers: 500 - 1 000 / year Network: 10-20 switches / year 2020: Servers: ~6 000 Disk arrays: ~1 000 Network: ~125 standard + ~10 high-bandwidth (40Gbs) switches 2021 – 2022: Servers: ~2 500 / year Disk arrays: ~500 / year Network: 50 standard + 5 high bandwidth switches / year A project for the construction of a 2nd DC on the CERN site is also in consideration for this timeframe.

  9. Others: Audiovisual equipment: all audio, video and control equipment installed in CERN meeting rooms desktop equipment tenders, which include: Desktop and mini desktops (NUCs) : 1300 Laptops: 550 Monitors 1500 Services, software: First line support for network & telecommunications services Computing Services Support (helpdesk and first line) Central Computing Facilities (CC operators) SW: service management, videoconferencing, open software for core services

  10. Collaborate and exchange ideaswithothercommunities to createknowledge and innovation. CERN OPENLAB’S MISSION (https://openlab.cern/) Our recipe for success Communicateresults, demostrate impact, and reach new audiences. Train the nextgeneration of engineers/researchers, promoteeducation and cultural exchanges. Evaluate and test state-of-the-art technologies in achallengingenvironment and improvethem in collaboration withindustry.

  11. Joint R&D Projects High-bandwidth fabrics, accelerated platforms for data acquisition Fast simulation, Data quality monitoring, anomaly detection, physics data reduction, benchmarking/scalability, systems biology and large-scale multi-disciplinary platforms Simulation, HPC on the Cloud, benchmarking Cloud federations, containers, scalability Predictive/proactive maintenance and operations Storage architectures, scalability, monitoring Software Defined Networks, Security
